  • create Arch Linux folder
  • Add HOOK/INSTALL files to generate a custom initrafms for boot on read-only snapshot for Arch Linux.
  • Add readme file to initramfs folder

Improvement:

• Script
  • Stop script if root partition isn't btrfs filesystem.
    Add filesystem check on the root partition.
    If the filesystem isn't btrfs, stop execution.
  • Update error message for btrfs-prog.
• Config file
  • Add new path to ignore docker subvolume.
    Many distributions now use "@" as the default subvolume.

    Fix: #110
  • Add 2 disctincs parameter to ignore path during run grub-mkconfig.
    GRUB_BTRFS_IGNORE_SPECIFIC_PATH=("")
    and
    GRUB_BTRFS_IGNORE_PREFIX_PATH=("")
    In specific path, only exact paths are ignored.
    In prefix path, any path starting with the specified string will be ignored.
    e.g :
    If specific path = "@", only "@" snapshot will be ignored.
    If prefix path = "@", all snapshots beginning with "@/..." will be ignored.
  • Rename "GRUB_BTRFS_DIRNAME" to "GRUB_BTRFS_GRUB_DIRNAME"
    Full path to Grub folder is now configurable (/boot is no longer hard coded).
